stratigraphic definition

stratigraphic means of or pertaining to the arrangement of strata; stratigraphy, the study of rock layers (strata) and the layering process (stratification); the layering of deposits, with newer strata overlying older ones, forming a chronology of the site; a stratigraphic cycle in a magmatic deposit is the cycle of the different layers;
stratigraphic means the composition, sequence and correlation of stratified rocks;
stratigraphic means the arrangement of sedimentary rocks in strata with reference to the different properties of the rocks;

Related to stratigraphic

  • stratigraphic test well means a drilling effort, geologically directed, to obtain information pertaining to a specific geologic condition. Ordinarily, such wells are drilled without the intention of being completed for hydrocarbon production. They include wells for the purpose of core tests and all types of expendable holes related to hydrocarbon exploration. Stratigraphic test wells are classified as (i) "exploratory type" if not drilled into a proved property; or (ii) "development type", if drilled into a proved property. Development type stratigraphic wells are also referred to as "evaluation wells".

  • Depth , in respect of a building, means the measured distance between the front line of the building and the back line of the rear main wall which separates the main building from the open space;

  • Hydraulic fracturing means the fracturing of underground rock formations, including shale and non-shale formations, by manmade fluid-driven techniques for the purpose of stimulating oil, natural gas, or other subsurface hydrocarbon production.

  • mineralization means the concentration of metals and their chemical compounds within a body of rock;

  • Infiltrative surface means designated interface where effluent moves from distribution media or a distribution product into treatment media or original soil. In standard trench or bed systems this will be the interface of the distribution media or product and in-situ soil. Two separate infiltrative surfaces will exist in a mound system and an unlined sand filter, one at the interface of the distribution media and fill sand, the other at the interface of the fill sand and in-situ soil.

  • Surface mining means mining by removing the overburden lying above the natural deposits and excavating directly from the natural deposits exposed, or by excavating directly from deposits lying exposed in their natural state and shall include dredge operations conducted in or on natural waterways or artificially created waterways within the state.
